  1. The CDC estimates that 6.5 million people use some sort of mobility aid, such as canes, walkers, rollators or crutches. Mobility aids can be of great assistance for elderly and disabled patients. However, patients often use their mobility aids incorrectly because they cannot tell how much weight they are putting onto them and lean on them too much....

  2. Shoulder Overuse Syndrome (SOS) occurs from repetitive motion and excessive load put on a shoulder. SOS can affect anyone, from athletes to blue collar laborers, however, wheelchair users make up a significant portion of the affected population. SOS results in swelling, stiffness, instability or inability to complete shoulder movements. In severe c...

  3. Wearability opens up a whole new world of opportunities in haptic systems for novel communication forms and interactions with the external environment. Wearable fingertip haptic systems are particularly interesting as they offer a natural interface to one of the most fundamental senses, touch. There are several types of cutaneous fingertip devices ...

  4. The aerospace industry is constantly developing testing techniques to improve efficiency, and reduce cost. One dilemma with current testing techniques on aircraft is the inability to accurately detect surface and subsurface defects. These defects are often caused by service induced cracks that can be a result of fatigue or stress corrosion. Additio...

  5. Silicon heterojunction (SHJ) technology can provide high solar cell efficiency and low cost in high volume manufacturing. Transparent conductive oxides (TCOs), a component in SHJ cells, can help achieve good conductivity and electrical contact with metals for transferring current. However, optimizing TCO layers in SHJ solar cells requires a tradeof...

  6. Low work function electrodes have the potential to advance and enable technologies that rely on electron transfer, such as electron sources utilizing thermionic electron emitters. Conventional electron sources based on metallic cathodes operate at temperatures exceeding 1000°C. Lowering the operating temperature would lead to a simpler design, ...

  7. Spatial changes during building construction usually manifest as deviations between the as-designed model and the as-built conditions. These deviations can lead to errors that result in delays and additional costs. Project engineers often spend significant time, money, and resources to manually track and analyze changes between the as-designed mode...

  8. Functional coatings are essential to the development of next generation products in the textile, display, automotive, energy, and health care industries. While the performance of nanomaterial coatings is widely successful in the lab, there is no general method to form these coatings at a larger scale. Current attempts lack precision, scalability, a...

  9. Complex 3D printed parts often require supports during the 3D printing process. While dissolvable supports are common in 3D printing for plastics, supports for metals and oxides have many limitations. Traditional, monolithic metal 3D printed supports often need to be machined off. This process is expensive and restricts part design, as the supports...

  10. Dissolvable supports are common in plastic 3D printing and dramatically simplify the cleanup process for plastic parts. However, this capability has not been extended to metal 3D printing, and metal 3D printed supports must be machined off. The increased costs of the process are sometimes more expensive than subtractive manufacturing and can exceed...
